LightnigFast/Project-Lightning ? reverse-engineered prompt

Build me a desktop app called Project Lightning that acts like an all in one gaming library manager and launcher.

I want users to be able to add games to a library, see cover art and basic game details, launch games from inside the app, and keep track of playtime automatically. It should also have a built in browse area for a game catalog, where people can search for games, view screenshots and details, and add things straight into their library.

Please include a download manager that can handle queued downloads, pause and resume, and extract common archive types after download. It should also support a few game fix and compatibility tools, plus simple Steam library integration. Make it feel fast, modern, and easy to use, with support for multiple languages and controller detection. If you need to look up current docs online for anything, go ahead.
